The hint portion of the problem states that it is not relativistic but I will check my calculations with it. Seeing as how the velocity I calculated is slightly under 0.006c though I am sure it is not. Part a is in eV and part b is in keV, so yes I am sure I can't see the answer without...

Homework Statement What is the De Broglie wavelength of an electron with KE= 8.5 eV? Homework Equations λ=h/p KE=0.5mv2 p=mv The Attempt at a Solution I converted 8.5 eV into joules: 8/5 eV × 1.602e-19 J = 1.3617e-18 Then used it for KE to solve for v: I got 1729006.11...

Haha of course! I feel silly for not thinking of that. Thanks so much TSny!

Homework Statement A solenoid of length 20.0 cm is made of 5000 circular coils. It carries a steady current of 10.0 A. Near its center is places a very flat and small coil with a resistance of 2.50 Ω made of 100 circular loops, each with a radius of 3.00 mm. This small coil is oriented so that...

Awesome, thank you so much, Infinitum!

Homework Statement You have 3 charges, all +2.5 μC arranged on a field at positions (-3.0 cm, 0), (3.0 cm, 0), and (0, 3.0 cm). I have already calculated the stored electric potential energy to be 3.85 J. The question is: If the third charge (0, 3.0 cm) is released from rest, what is its change...
